step six, drying by 2-3 drying ovens, setting the temperature of the drying ovens to be 75-85 ℃, setting the speed to be 100-,
and seventhly, completely drying and rolling to obtain the thermal sublimation transfer printing paper.
Example 2 (preparation method 2):
step one, preparing a first coating, weighing according to the weight ratio: 19 parts of sodium carboxymethylcellulose, 16 parts of polyoxyethylene, 12 parts of polyacrylic acid-2-ethylhexyl ester and 2 parts of dispersing agent are put into water, and after the mixture is uniformly stirred at room temperature, 9 parts of nano titanium dioxide, 7 parts of nano magnesium oxide and 11 parts of nano silicon nitride are added, and the mixture is continuously stirred at room temperature for 60min to prepare coating glue with the solid content of 18-26% for later use.
Step two, preparing a second coating, weighing according to the weight ratio: 55 parts of 1, 2-dihydroxy-3-trityl-propane, 26 parts of a film forming agent and 19 parts of a filler. Stirring at room temperature for 60min to obtain coating glue with solid content of 15-22%.
And step three, selecting proper base paper.
Step four, applying 3-7g of the materials in the step two on the front surface of the base paper,
step five, drying by 2-3 drying ovens, setting the temperature of the drying ovens to be 75-85 ℃, setting the speed of the oven to be 100-,
step six, drying by 2-3 drying ovens, setting the temperature of the drying ovens to be 75-85 ℃, setting the speed to be 100-,
and seventhly, completely drying and rolling to obtain the thermal sublimation transfer printing paper. The two embodiments described above both use the same principle of action, specifically:
the thermal sublimation rendition will be with the mode that the printing paper of thermal sublimation rendition ink was printed passes through the hot pressing, thereby the fixed dyestuff sublimation completes the transfer of pattern on the messenger rendition paper. The temperature rise speed and the heating uniformity of the transfer paper directly affect the sublimation of the dye and the color uniformity of the transfer picture.
Materials with high heat conductivity coefficient such as aluminum nitride and magnesium oxide are introduced into the first coating, the first coating can permeate into the base paper, the heat conductivity of the base paper can be improved to a certain degree, and the temperature rise of the transfer paper can be effectively accelerated in hot pressing. Simultaneously, this coating can effectively weaken the phenomenon that the ink oozed to base paper down when printing to weaken the reverse sublimation of dyestuff to the condition of base paper in the rendition, then effectively promote the effective sublimation rate of dyestuff, improve the transfer rate that changes printing paper.
1, 2-dihydroxy-3-trityl-propane micromolecules are introduced into the second coating, the second coating is a novel efficient thermal sublimation functional material, and the molecules have more action sites and can act with a plurality of dye molecules. Meanwhile, the 1, 2-dihydroxy-3-trityl-propane material has efficient release performance on dye molecules in hot pressing, reduces resistance borne by the dye molecules in a sublimation process, enables the dye molecules to be sublimated fast and efficiently, and can effectively improve the thermal sublimation performance of the coating.
Based on the above embodiments, the present invention further performs the following two performance tests, specifically:
1. penetration test
